A Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process.
Rotary Kiln
A Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include:
Cement
Lime
Refractories
metakaolin
Titanium dioxide
Alumina
Vermiculite
Iron ore pellets
Bauxite
......
Principle of Operation:
The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. contact with via skype:gary102884 if need our machinery. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal.
Kiln Shell
This is made from rolled mild steel plate, usually between 15 and 70 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. This will be usually situated on an east/west axis to prevent eddy currents.
